Really, use Google and the Wiki. There are thousands of good articles out there about Intel processors, about computer architectures, and about the x86 series (and in particular about the 80x86 and the 80386/387 processors).

Just for the record, "86" comes from the 8086, which was the first 16 bit general purpose microprocessor from intel, along with the 8088. However, when people nowadays talk about "x86", they really meant "80386 and above", since that was the first x86 cpu capable of operating in 32 bits mode.

No current software that runs in 32 bits protected mode will ever run in anything below the 80386 chip. Again, search the net, this is perfectly explained in thousands of places, it would be idiotic to replicate that info here, and prone to errors (there's already a good lot of them above...).

Well, no, X86_64 requires a compatible 64-bit AMD or Intel processor--not just AMD.

Well, this is confusing,

I'm running a Amd 64 bit chipset and arch returns i686.

On my dinosaur PII 400mhz laptop I also get i686.

I guess I can download both the i386 and x86_64 and see which one will load.

What chipset? You could look up your CPU's specs to see if it can do 64 bits.

i386 will load regardless; the consumer x86_64 chips can run i386 and x86_64.

Run
Code:
cat /proc/cpuinfo
and on the "flags" line look for "lm". If it's there, your CPU can do long mode or 64-bits.

The "lm" flag is what you should look for, as said above.

arch will return the arch your OS was compiled for, which is not relevant since as said, an x86_64 cpu can work in both x86_64 and x86 modes.

The known 64 bit machine is a AMD x2-64 4000
But it is running the 32 bit version of linux
and the lm flag is reported


The laptop was made before 64 bit proc's and os were on the market so i383 arch is the os to install.

this entry might also be of use
clflush size : 64
versus
clflush size : 32

I was originally thinking that the install application on the cd's/dvd's would scale to the processor. But now I think my logic was flawed.
